With a change in times, and increasing individualistic needs of the businesses, VoIP services is becoming an essential part of the communication of all the segments of the industry. It is becoming a hot favorite of everyone from business to residentials mainly because of its ability to offer best rates without hampering the quality of calls. In the quality parameter, it stands neck to neck with the traditional PSTN or PBX telephony services.

Keeping in mind its cost effective feature, it becomes the main criteria for opting for a VoIP service provider by most of its clients. In order to test the quality of calls that would be provided by the provider, one can ask for a testing of the routes. This would help enable the clients to make the right decision, since it would be based on pre-testing and not just promises of good quality by the provider.

Moreover, clients can also check the quality by 3 parameters on which quality is tested, namely, Average call duration (ACD), Average success ratio (ASR) and Post duration delay (PDD). ACR between 6-7 minutes would give you average quality and above 7 would give excellent quality. Similarly, ASR between 50-55% is average while above 55% is excellent. On the same lines, PDD below 3-4 seconds is average, while below 2 seconds is considered excellent.

There are some premium providers who give the wholesale carrier service providers and resellers the freedom to select their own tariffs that they would charge from their clients, unlike those providers of voice over IP who work on commission basis. The right to charge the rates according to their discretion would enable the resellers and wholesalers to earn a higher profit accordingly.

Besides, both wholesalers and resellers should affirm that a continuous technical support would be provided to them, so as to help in the smooth functioning of the working of the organisation. It must not be forgotten that the end customer would be getting a service and not a tangible product. A service would be judged on the basis of its quality of working.
